Seabed mapping data from remote sensing and groundtruth samples taken at East of Haig Fras Marine Conservation Zone from 2012 to 2015

As described in the manuscript entitled "Limitations of predicting substrate classes on a sedimentary complex but morphologically simple seabed" remotely sensed variables and ground truth samples were distributed as part of a seabed mapping exercise. This holding contains the four raster layers provided to all participants for the East of Haig Fras MCZ and the groundtruth samples. These four rasters are: Multibeam echosounder bathymetry, multibeam echosounder backscatter, modelled maximum current velocity at the seabed and...

Consistent concentrations of critically endangered Balearic shearwaters in UK waters revealed by at-sea surveys

Jessica Ann Phillips, Alex N. Banks, Mark Bolton, Tom Brereton, Pierre Cazenave, Natasha Gillies, Oliver Padget, Jeroen Van Der Kooij, James Waggit & Tim Guilford
Aim: Europe’s only globally critically endangered seabird, the Balearic shearwater (Puffinus mauretanicus), is thought to have expanded its post-breeding range northwards into UK waters, though its distribution there is not yet well understood. This study aims to identify environmental factors associated with the species’ presence, and map the probability of presence of the species across the western English Channel and southern Celtic Sea, and estimate the number of individuals in this area. Location: The western...

Plankton Imager zooplankton data, acoustic fish biomass estimates, chlorophyll measurements and CTD data from the Celtic Sea and Western English Channel in October 2018

Zooplankton species and size data from the Plankton Imager taken from the Celtic Sea and Western English Channel onboard the RV “Cefas Endeavour” in October 2018, also included are pelagic fish biomass estimates from acoustics, chlorophyll measurements and temperature and salinity data from CTDs. All data were recorded as part of the annual PELTIC survey (Pelagic ecosystem in the western English Channel and eastern Celtic Sea). During the day, multifrequency acoustic data are acquired along...

Data from: Projected impacts of warming seas on commercially fished species at a biogeographic boundary of the European continental shelf

Katherine Maltby, Louise Rutterford, Jonathan Tinker, Martin Genner & Stephen Simpson
1. Projecting the future effects of climate change on marine fished populations can help prepare the fishing industry and management systems for resulting ecological, social and economic changes. Generating projections using multiple climate scenarios can provide valuable insights for fisheries stakeholders regarding uncertainty arising from future climate data. 2. Using a range of climate projections based on the Intergovernmental Panel on Climate Change A1B, RCP4.5 and RCP8.5 climate scenarios, we modelled abundance of eight commercially...

Marine stepping-stones: Connectivity of Mytilus edulis populations between offshore energy installations

Joop W.P. Coolen, Arjen R. Boon, Richard Crooijmans, Hilde Van Pelt, Frank Kleissen, Daan Gerla, Jan Beermann, Silvana N.R. Birchenough, Lisa E. Becking & Pieternella C. Luttikhuizen
Recent papers postulate that epifaunal organisms use artificial structures as stepping-stones to spread to areas that are too distant to reach in a single generation. With thousands of artificial structures present in the North Sea, we test the hypothesis that these structures are connected by water currents and act as an interconnected reef. Population genetic structure of the Blue mussel, Mytilus edulis was expected to follow a pattern predicted by particle tracking models (PTM). Correlation...

Benthic Genera Presence and Absence in the North Sea from 1990 to 2011

Distribution data for benthic genera in the North Sea, covering a 22-year timespan from 1990 to 2011. This data accompanies the manuscript “Capturing threshold responses of marine benthos along gradients of natural and anthropogenic change”, by E. Couce, G.H. Engelhard and M. Schratzberger, Journal of Applied Ecology, in press. It was obtained from re-analysis of OBIS benthic data supplemented with benthic survey data collected by Cefas in the same period, with the study region partitioned...

CLiP Belize Marine Litter Abundance and Composition 2019

This dataset contains 2 csv files. The file Belize_Marine_Litter_Data.csv contains data on litter found on marine beaches, river banks and along city canals in Belize between May and June 2019. The number of items and the weight in kg is reported for each litter category. The list of litter categories was obtain merging OSPAR and Tangaroa Blue protocols with the addition of region-specific items. Item categories marked with '*' were added during the operations in...

Data from: Species interactions and environmental context affect intraspecific behavioural trait variation and ecosystem function

Camilla Cassidy, Laura J Grange, Clement Garcia, Stefan Bolam & Jasmin A Godbold
Functional trait-based approaches are increasingly adopted to understand and project ecological responses to environmental change; however, most assume trait expression is constant between conspecifics irrespective of con- text. Using two species of benthic invertebrate (brittlestars Amphiura filiformis and A. chiajei), we demonstrate that trait expression at individual and com- munity levels differs with biotic and abiotic context. We use PERMANOVA to test the effect of species identity, density and local environmental history on individual (righting...

Balancing risks of injury and disturbance to marine mammals when pile driving at offshore windfarms

Paul Thompson, Isla Graham, Barbara Cheney, Tim Barton, Adrian Farcas & Nathan Merchant
1. Offshore windfarms require construction procedures that minimise impacts on protected marine mammals. Uncertainty over the efficacy of existing guidelines for mitigating near-field injury when pile-driving recently resulted in the development of alternative measures, which integrated the routine deployment of acoustic deterrent devices (ADD) into engineering installation procedures without prior monitoring by Marine Mammal Observers. 2. We conducted research around the installation of jacket foundations at the UK’s first deep-water offshore windfarm to address data...

Data from: Using structured eradication feasibility assessment to prioritise the management of new and emerging invasive alien species in Europe

Olaf Booy, Peter A. Robertson, Niall Moore, Jess Ward, Helen E. Roy, Tim Adriaens, Richard Shaw, Johan Van Valkenburg, Gabe Wyn, Sandro Bertolino, Olivier Blight, Etienne Branquart, Giuseppe Brundu, Joe Caffrey, Dario Capizzi, Jim Casaer, Olivier De Clerck, Neil Coughlan, Eithne Davis, Jaimie Dick, Franz Essl, Guillaume Fried, Piero Genovesi, Pablo González-Moreno, Frank Hysentruyt … & Aileen C. Mill
Prioritising the management of invasive alien species (IAS) is of global importance and within Europe integral to the EU IAS regulation. To prioritise management effectively the risks posed by IAS need to be assessed, but so too does the feasibility of their management. While risk of IAS to the EU has been assessed, the feasibility of management has not. We assessed the feasibility of eradicating 60 new (not yet established) and 35 emerging (established with...

The file South_Africa_Marine_Litter_Data.csv contains data on marine litter found during beach surveys in Umhlanga (north of Durban) and Amanzimtoti (south of Durban) in South Africa in September 2019. The number of items and the weight in kg is reported for each litter category. Each survey is named with the name of the location plus a capital letter between A and L for Amanzimtoti; and between A and K for...

Seafloor Marine Litter from UK EEZ zones between 2012 and 2017

This data set was used to assess the density of litter in the seafloor for the MSFD indicator assessment that was completed in 2018 and published in 2019 at https://moat.cefas.co.uk/pressures-from-human-activities/marine-litter/seafloor-litter. The data contained counts of each type of litter category. The data is contained in the file, litter 2017 new.csv. Details on what the data columns mean are shown in the readme file. Data is only from the UK EEZ zone. This is made up...
